Why Insurers May Deny CTP Claims in NSW

A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).

Insurers may deny a Compulsory Third Party (CTP) claim in New South Wales for several reasons, including disputes over fault, misclassification of injuries, or failure to meet eligibility criteria. Under the Motor Accident Injuries Act 2017, claims must demonstrate a threshold injury or meet specific statutory benefit conditions. For example, if a claimant’s injuries are classified as a 'threshold injury' but the insurer disputes this, benefits may be denied. Insurers also often challenge claims where evidence is incomplete or where the claimant has not followed required procedures.

Common Reasons for CTP Claim Denials

  1. Fault Disputes: Insurers may deny claims if they dispute the other party’s responsibility for the accident. CTP claims are based on fault, so the insurer must accept liability before benefits can be paid.
  1. Threshold Injury Misclassification: Under the Motor Accident Guidelines, injuries must meet specific clinical criteria to qualify as 'threshold injuries.' If an insurer disagrees with the medical assessment, they may deny benefits.
  1. Lack of Evidence: Insurers often reject claims where medical records, accident reports, or witness statements are incomplete or inconsistent. For example, a claimant must provide evidence of treatment and ongoing consequences to qualify for weekly income payments.
  1. Eligibility for Statutory Benefits: The 52-week statutory benefit period applies only if the claimant’s injuries are 'threshold injuries.' If the injuries are more severe, benefits may continue beyond 52 weeks, but insurers may dispute this.

How to Challenge a Denied CTP Claim

If an insurer denies your claim, you can challenge the decision by:

  • Reviewing the Denial Letter: Insurers must provide a written explanation for their decision. Carefully examine the reasons given and check if they align with the Motor Accident Injuries Act 2017.
  • Gathering Evidence: Collect all relevant documents, including medical records, accident reports, and witness statements. For example, if the insurer disputes the severity of your injuries, provide clinical evidence from a registered medical practitioner.
  • Contacting SIRA: The State Insurance Regulatory Authority (SIRA) oversees CTP claims and can mediate disputes. You can lodge a complaint with SIRA by submitting a written request explaining your case.
  • Seeking Independent Medical Advice: If the insurer’s assessment of your injuries is disputed, consult a medical practitioner who specializes in motor accident injuries. Their opinion may be required to challenge the denial.

The Role of SIRA in Resolving CTP Disputes

SIRA is the primary authority for resolving disputes over CTP claims. If an insurer denies a claim, you can request a review by SIRA. SIRA will assess whether the insurer’s decision is legally sound and may require the insurer to reconsider the claim. In some cases, SIRA may refer the matter to a formal review process or mediation.

Example: A Claimant’s Case

Consider a scenario where a pedestrian in Western Sydney is injured in a car accident. The insurer denies the claim, arguing the injuries are 'threshold injuries' and benefits should stop after 52 weeks. However, the claimant’s medical records show ongoing neurological symptoms that meet the Motor Accident Guidelines’ criteria for a more severe injury. In this case, the claimant can challenge the denial by providing the medical evidence and requesting a review by SIRA.

Next Steps After a CTP Claim is Denied

If your CTP claim is denied, take the following steps:

  1. Review the Denial Letter: Understand the specific reasons for the rejection.
  1. Gather Evidence: Collect all relevant documents to support your claim.
  1. Contact SIRA: Lodge a complaint with SIRA to challenge the insurer’s decision.
  1. Seek Legal Advice: If the dispute escalates, consult a solicitor who specializes in CTP claims. They can help you navigate the legal process and ensure your rights are protected.

Time Limits and Procedural Deadlines

CTP claims must be submitted within a specific timeframe. While there is no strict time limit for lodging a claim, delays may affect your ability to challenge a denial. For example, if the insurer denies a claim after 52 weeks, you may need to demonstrate that the injuries are not threshold injuries to continue receiving benefits.
